DC World, Metropolis.

Wonder Woman, armed with a shield and an ancient sword, appeared on the streets of the Metropolis, apparently wary of something.

"Superman, are we strong enough to defend here?" Diana looked at Superman and asked suspiciously.

"That's right, I've heard about an alien invasion, and it has something to do with it." Superman thought for a moment and said affirmatively.

Diana's identity is not simple, his brother is the god of war Ares, and her body has the blood of Zeus, so she can exert unparalleled power.

When she was a child, Diana came from the Amazon tribe, and it was not until later that she appeared in the metropolis, and the twists and turns can be imagined.

Suddenly, while Superman and Diana were chatting, the phone vibrated and Superman turned on the phone and heard Dr. Stone's name.

"Dr. Stone, how's it going?" Superman asked, looking at Dr. Stone.

"The situation is not good, the radiation and energy are intensifying, and the Met may face a crisis." Dr. Stone said with a frown.

"I see, I'll call the Justice League if I need to."

Superman thought about it for a moment and made the right choice.

"Diana, we need to be here for a while, you have no problem!" Superman asked, looking at Diana.

"Of course not." Diana said without hesitation.

At this time, in the state-of-the-art laboratory in Midtown, Sisko and Dr. Wells were conditioning a special instrument, as if they were preparing something.

"Doctor, aren't we going to the Metropolis to help?" Barry asked suspiciously, as he worked.

"I'm sorry, Barry we're working on it, we've learned from the last Kryptonian invasion, we can give the aliens a hard hit this time."

Sisko said excitedly, constantly adjusting various instruments, obviously there is a better choice.

"That's it! I'm interested, can I help? Tang Tian walked over and said confusedly.

The DC world has hidden a lot of black technology, especially in dangerous times, and it is even the time for the outbreak of black technology, and there is even a certain possibility of researching anti-sky technology.

"Of course, you can help you, I heard that you have developed nanotechnology! It just so happens that I need you to craft one thing, which is a weapon. ”

Dr. Wells pushed his glasses and spoke carefully.

"That's it! You say! As long as there are drawings I can help. Tang Tian looked at Dr. Wells and said softly.

When Tang Tian came back a few days ago, he told Dr. Wells about the nanotechnology he had developed, and he thought that he would basically not use it, but he didn't expect that it would be useful one day.

Dr. Wells also nodded to Tang Tian without hesitation, and he opened a drawing, which actually depicted a small particle accelerator, and there was a cannon barrel extending on it.

"OMG! Dr. Wells, you don't want to make a particle booster! Sisko said dumbfounded.

Just by listening to the name, you can know the danger of the particle accelerator, not to mention the miniaturized particle accelerator, which is simply a huge bomb, and it is estimated that most of the metropolises will not be able to protect it if it explodes with all its might.

"Answer correctly, but no reward." Dr. Wells said with a blank face.

Speaking of the situation, Dr. Wells has no talent for humor, and he doesn't like to joke about anything, and it is this personality that ensures that Dr. Wells has an attitude of almost doing what he says.

"In this way, high pressure and high energy need special materials to protect it, and the materials on the earth cannot resist it."

Sisko frowned and analyzed.

Originally, what Dr. Wells said was almost impossible to achieve, but whoever wants to have Tang Tian's backup, it is impossible to appear that the other party has nanotechnology.

"That being said, we can synthesize a special alloy, and it should be fine." Dr. Wells considered the feasibility and said seriously.

"Metal? I'm able to craft a few metals, enough to withstand the energy of a particle accelerator. ”

Tang Tian thought of the Edelman alloy and vibranium, and in addition to that, there was also a special metal like Ulu alloy, so he nodded to Dr. Wells and said.

Tang Tian has been to the Marvel world, and Asgard has been to a little bit, but it has brought a little trouble to Thor, and with Tang Tian's idea, he can basically process a cosmic-level metal by fusing the power of the three alloys.

It is estimated that unless the Big Bang, it is estimated that the particle accelerator cannon will not cause any problems, so Dr. Wells's seemingly fantastical plan is still possible.

"You have such metal." Dr. Wells said, with a twinkle in his eyes.

"That's right." Tang Tian looked at Dr. Wells and nodded.

"Is there a sample? I'm going to test it. Dr. Wells said excitedly.

"Of course, give me time to prepare, and I'll give it to you right away."

Tang Tian looked at Dr. Wells and explained.

"That's good." Dr. Wells said with relief.

Actually, Dr. Wells also wanted to ask Tang Tian about the origin of these metals, but thinking of Tang Tian's mysterious appearance, he knew what he should do.

The crisis they are facing now is that Darkseid can only deal with other things if he solves this trouble, so Dr. Wells is still very clear.

"By the way, Doctor, why do you think the enemy is stronger than General Zod this time?" Sisko looked at Dr. Wells and asked softly.

"The reason is very simple, that is, just an ordinary subordinate of the other party has the strength to fight two superheroes, not to mention the person who controls them."

Dr. Wells is also a well-informed person, so he will not do useless work, and he can only think through such a situation.

"You're right, Doctor, it's just that if the aliens are hit, they won't gain more power."

Sisko said with some skepticism that the particle accelerator cannon contained a lot of energy, so they also needed to pay attention to it.

"Since he is the strongest enemy, he must have the energy of the particle accelerator cannon, so when another energy hits him."

Dr. Wells smiled and explained indifferently.

"The two forces will clash, and that guy will be hit hard." Sisko said excitedly.

"Yes, that's it." Wells said undeniably.

"It's just that what we should consider is the charging time of the particle accelerator cannon, and the other party is not weak."

Tang Tian looked at Dr. Wells and said remindedly.

"I also know this, and I hope there is a possibility of improvement." Dr. Wells thought for a moment and said solemnly.
